I would advise you guys to keep a look at Ardor and Xrb! the first might be already on a higher cap but has easily a 5x potential next year. Where xrb is the more risky bet but certainly with higher possible gains since the actual market cap is really low.

I would bet everything in that Golem and Digibyte and one of the most promising altcoins that will ever exist, i am in love with those coins because they have a lot of support in China, and in the whole Asia too.But there are a few more cryptos that will increase by a lot of money during this last two months left until we are on 2018. 0xproject is a very good coin too, but it is freezed, i dont know why it is not increasing, it is weird.

I have ripple coin and I think uts better to invest ti that coin because in my own resesrch I see the potentiam to increase the price in the future but it depends on the demand on the market. But the percentage is very high. But it's your coice if you buy ripple. You can make a research so you can know what coin is the best to you that gives you high profit in the future. Be careful of what you invest.
